| Abstract: | Multi-fault diagnosis is a puzzle for the complicated system such as satellite.A diagnosis method based on the dynamic observer is researched.The structure of dynamic observer is modified to make it to be robust to a fault.So,the complexity of designing a family observer is reduced.The design method of dynamic observer and the strategy of multi-fault diagnosis are proposed.The diagnosis technology is applied to a satellite attitude control subsystem.The result of simulation proves that the method is suitabl... |
